Using the Peter Parente's "webcam capture" library (Webcam Continuous Capture.vi), I faced some problems. In fact instead of showing for example one 320*240 picture it displayed some smaller pictures with some other parts of the "picture indicator" left blank(black). What's the problem. Any help would be appreciated.
That sounds like a 3rd party library of VIs, so you may try contacting the author of that library for more help. I haven't used them before, but perhaps someone else in the community has!
